Pat Shingleton: "Check Your "Cold" Cholesterol"
Colder weather may increase cholesterol levels. "The Atlantic" reports that research, conducted in Brazil, found that an 8% increase occurred in colder weather than tests conducted during the summer months. Original studies verified that heart attacks happen more often during the winter months and the reasons could be more stress due to the holidays and strenuous activities such as snow shoveling. Researchers believe that less sun exposure in the winter may be a key to the variation since vitamin D improves the ratio of good and bad cholesterol levels. Another component of the study is the obvious dynamic of increased food consumption and less exercise in colder weather. Scientists conducted the research in a tropical climate, noting that fluctuations could be greater where seasonal climate shifts are more dramatic.
